# NAME
#  custodian-enqueue - Insert sentinel-probes into a queue.
#
# SYNOPSIS
#  custodian-enqueue  [ -h | --help ]
#                     [ -m | --manual]
#                     [ -f | --file FILE]
#                     [ -d | --dump ]
#                     [    | --test ]
#
# OPTIONS
#
#  -h, --help          Show a help message, and exit.
#
#  -m, --manual        Show this manual, and exit.
#
#  -d, --dump          Dump the parsed tests to the console; don't insert in the queue.
#
#  --test              Test the parsing of the given file, alert on errors.
#
#  -f, --file FILE     Parse the given configuration file.
#
#
#
# ABOUT
#
#  This tool reads a single configuration file and parses it into a
# series of network & protocol tests.   These tests are then stored in
# a beanstalkd queue.
#
#  The intention is that the tests will be pulled from the queue and
# executed by the companion program custodian-dequeue.  The dequeing
# process may occur up numerous other hosts
#
# CONFIGURATION FILE
#
#  The configuration file is 99% compatible with that used in the tool
# custodian replaces.
